I did build it up gradually, but as you would guess this is the part I picked up on:
People with serious ailments have been shown to benefit from higher dosages, up to four 1-gram tablets three times daily. Such a high dosage may be advised to fight parasital infections. Case studies have been reported in which patients did not show noticeable improvement until they received a daily dosage of 30 grams (6). Such extreme dosage is not generally recommended for most people, although no negative effects were reported (3,6).
